Description
Technical field
The invention belongs to steel processing technique fields, and in particular to a kind of surface acidation treatment method of steel.
Background technique
Surface cohering technology is the composite material adhesive coated that is formed with high molecular polymer and particular fillers in part
Realize the new technology of certain purposes in surface.The method for improving interface binding intensity is mainly divided to two aspects, and first is that change is compound
The ingredient of the binder of material improves its cohesive force by achieving the effect that binder modification.Second is to metallic matrix
Surface preparation is carried out, this is also an important factor for influencing binder/metal interface adhesion strength.Before bonding, to metal
Surface carries out a series of processing to remove oxidation on metal surface layer and dust etc., forms new surface, metal interface can be improved
The intensity of bonding.The processing method of metal surface is broadly divided into Mechanical Method and two kinds of chemical method.Wherein chemical method is because of processing side
Formula is relatively simple and is widely adopted.Acidization be it is existing processing steel surface one of main method, but its there are still places
Manage the problem of time is longer, treatment effect is unable to reach people's dreamboat.
Summary of the invention
The present invention is intended to provide a kind of surface acidation treatment method of steel, existing acidification technique can be effectively shortened
Duration promotes the treatment effect of steel.
The present invention is achieved through the following technical solutions:
A kind of surface acidation treatment method of steel, includes the following steps:
(1) steeis pretreament:
A. steel to be processed are put into clear water spare after washing off impurity；
B. will operation a treated that steel are put into industry goes to carry out ungrease treatment in oil liquid, washed away after the completion with clear water residual
It is spare after liquid；
(2) steel acidification:
A. weighing corresponding substance by weight, to be configured to acidification liquid spare, in the acidification liquid each substance at
The weight percent divided are as follows: 10 ~ 12% hydrochloric acid, 2 ~ 4% tartaric acid, 2 ~ 3% neopelexes, 1 ~ 2% calcium stearate, 3 ~ 5%
Silica, surplus are water；
B. by step (1) treated steel the are immersed in operation resulting acidification liquid of a, pressurization keeps acidification
The pressure of liquid is 3 ~ 4MPa, and carries out mechanical stirring processing to acidification liquid, and keeping the flow velocity of liquid at steel surface is 2.5
It is taken out after ~ 2.8 m/s, 6 ~ 8min of coprocessing spare；
(3) cleaning treatment:
By step (2), treated, and steel are put into deionized water, at the same be aided with frequency be 35 ~ 38kHz ultrasonic wave into
Row cleaning, after completion carries out drying and processing under conditions of being placed on 65 DEG C.The ultrasonication of application is conducive to silica
The removal of powder ensure that the surface characteristic of original steel.
Further, silica described in step (2) operation a passes through special crushing and classification processing operation, specifically
It is that be ground into granular size for the 80 ~ 85% of total weight of silicon dioxide be 70 ~ 100 μm, the silica of remaining weight is ground into
Grain size is 1 ~ 30 μm, after being finally mixed again uniformly.Reasonable gradation can effectively promote the quarter of steel surface
Complexity is lost, the adhesion effect of binder is enhanced, improves the surface quality of steel.
Further, deionized water described in step (3) is heated to 30 ~ 33 DEG C.
The invention has the following beneficial effects:
Acidation treatment method of the present invention changes the processing mode of traditional simple acidleach, to acidification liquid and processing mode
Improved, wherein the removal of steel surface oxide layer, impurity etc. has been effectively ensured in unique acidification liquid prepared, and is had
There is appropriate etching performance, the silica composition added thereto can effectively promote the effect of acidification etching, in acidification
When to acidification liquid stirring during, silica composition is continuously flowed in steel surface strenuous exercise, or with liquid, or
It is attached in the micropore of the steel surface etched by acidleach, improves the roughness and micropore complexity on surface, further increase
The strong adhesion strength at steel interfaces, while during liquid constantly flow, it is formd between etching micropore partially communicating
Phenomenon improves adhesion strength conducive to the filling of binder.Final acidation treatment method of the present invention can effectively promote the viscous of steel
Knotting strength, and whole handling duration is shortened, application and popularizations value is higher.
